This aFe Silver Bullet throttle body spacer (part 46-34008) installs between your throttle body and intake manifold to increase plenum volume and improve air/fuel atomization. The helix-bored internal profile creates a mild tumble that keeps heavier fuel droplets suspended in the incoming air stream. It is a simple bolt-on that sharpens throttle response, particularly at low RPM.

Machined from 6061-T6 billet aluminum with a silver anodized finish, this spacer adds approximately 1 inch of plenum depth. The internal spiral grooves induce a vortex that helps atomize fuel before it enters the intake manifold runners. This can improve low-end torque by 5-10 lb-ft depending on application. A precision gasket is included for a leak-free seal.

Installation takes about 20 minutes. Unbolt the throttle body from the intake manifold, place the spacer between them with the included gasket, and re-torque to factory specifications. No tuning or check engine lights. Compatible with stock and aftermarket air intake systems.

Frequently Asked Questions

How much horsepower can the aFe Silver Bullet Throttle Body Spacers 46-34008 add to my V8 or V6 engine?

The aFe Silver Bullet Throttle Body Spacers 46-34008 typically adds 5 to 10 horsepower and 8 to 12 lb-ft of torque on most V8 and V6 applications. This throttle body spacer creates a swirling effect that improves air-fuel atomization before entering the intake manifold. The increased turbulence enhances low-end torque, especially below 3,500 RPM where daily driving occurs.

Does the aFe Silver Bullet Throttle Body Spacers 46-34008 improve throttle response on my daily driver vehicle?

Yes, the aFe Silver Bullet Throttle Body Spacers 46-34008 significantly improves throttle response by smoothing and swirling the incoming air charge. This throttle body spacer is typically 1/2 to 1 inch thick and installs between the throttle body and intake manifold. You will notice crisper acceleration from a stop and improved mid-range pull when merging onto highways.

Will the aFe Silver Bullet Throttle Body Spacers 46-34008 bolt directly between my throttle body and intake manifold?

The aFe Silver Bullet Throttle Body Spacers 46-34008 is designed with the exact bolt pattern and port matching for your specific throttle body and intake manifold combination. This throttle body spacer includes a gasket on both sides for a leak-free seal. Installation takes about 20 to 30 minutes with basic hand tools and does not require any modifications.

Can the aFe Silver Bullet Throttle Body Spacers 46-34008 help improve my vehicle overall fuel economy during daily driving?

Yes, the aFe Silver Bullet Throttle Body Spacers 46-34008 can improve fuel economy by 1 to 2 miles per gallon by enhancing air-fuel mixing efficiency. This throttle body spacer creates a helical swirl pattern that better atomizes fuel droplets for more complete combustion. The improved atomization means you get more energy from every drop of fuel under light to moderate throttle.

What material is the aFe Silver Bullet Throttle Body Spacers 46-34008 made from and how durable is it?

The aFe Silver Bullet Throttle Body Spacers 46-34008 is CNC-machined from 6061-T6 billet aluminum and anodized for corrosion resistance. This throttle body spacer measures 1/2 to 3/4 inch in thickness and weighs approximately 8 to 12 ounces. The precision-machined interior features a specific spiral vortex design to maximize air swirl without restricting overall airflow.

Does the aFe Silver Bullet Throttle Body Spacers 46-34008 require any ECU tuning or reprogramming after installation?

No, the aFe Silver Bullet Throttle Body Spacers 46-34008 does not require any ECU tuning or reprogramming after installation. This throttle body spacer is a purely mechanical bolt-on device that the engine computer automatically compensates for. Simply install it with the provided gaskets, torque the bolts to 8 to 12 ft-lbs, and you are ready to drive.
